In daily life, air conditioner is one of the necessary household appliances for people, especially in summer and winter, the frequency of use of air conditioner is very high, and people are increasingly relying on it. So what is the role of air conditioning capacitors and how to buy air conditioning capacitors?
What is the role of air conditioner capacitors?
The air conditioner capacitor is a device that starts the motor. If the motor does not rotate after being energized, it means that the capacitor is broken. Once the capacitor is damaged, the air conditioner will not work properly. Therefore, the capacitor is a very important component of the air conditioner. The method of checking whether the capacitor is damaged can be measured with the ohm gear of the pointer multimeter. If the deflection of the pointer is relatively large, it means that the capacitor has been damaged, and the capacitor of the air conditioner needs to be replaced in time.
How to choose and buy air conditioning capacitors?
1. When purchasing a capacitor, firstly observe the appearance of the capacitor, and observe whether the performance is deformed, cracked, or leaking oil. If this is the case, do not buy it, there must be quality problems. In addition, pay attention to whether it is the same specification and model as the one that needs to be replaced. You cannot just buy a specification and model to replace it, which will damage the air conditioner.
2. Secondly, when you are buying a capacitor, you also need to look at its capacity (the allowable deviation of the capacity of air-conditioning capacitors is ±5%). The capacity of the capacitor will generally decay with the longer the use time or the change of the environment. , If the capacitor capacity decays to 20%, it will make the air conditioner difficult to start.
3. When purchasing air conditioner capacitors, try to buy some well-known brand products. After all, the quality of big brands is more guaranteed and the use of air conditioners is also better.
4. There is one more thing to pay attention to when buying capacitors. Many people think that small stores are much cheaper than regular physical stores, so they go directly to small stores to buy them. In fact, this is an unwise choice. Although the products of small shops are cheap, there is no quality guarantee, and air conditioners are very important home appliances.
